MOULD STEEL D2
D2=1.2379=SKD11=Cr12Mo1V1
Usage: Applied in thickness no less than 2mm punch mould, all kind of small mould for shearing and cutter together with screworolled or slappered mould as well as some other forming mould like rulers.
Characteristic: E. S. R. Materials, high compression strgth and fine robustness. The spheroical annealed make it easily processed by shearing and cutting with no crake while processing.
